📊 Radians vs Degrees
Trigonometric functions can be calculated in radians or degrees. Radians are the default mathematical unit (π rad = 180°). Use the DEG/RAD button to switch modes.
💡 Memory Functions Explained
M+ (Memory Add): Adds current displayed value to memory
M- (Memory Subtract): Subtracts current displayed value from memory
MR (Memory Recall): Displays the stored memory value
MC (Memory Clear): Clears (resets) memory to zero
❓ Frequently Asked Questions
What is the difference between radians and degrees?
Radians and degrees are two units for measuring angles. A full circle is 360 degrees or 2π radians. Most mathematical calculations use radians by default.
How do I calculate powers (exponents)?
Use the xʸ button. First enter the base number, then press xʸ, then enter the exponent, and press =.
What is the factorial function (n!)?
Factorial (n!) multiplies all positive integers from 1 to n. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120.
Can I use keyboard shortcuts?
Yes! Use number keys (0-9), operators (+, -, *, /), Enter for =, Backspace for delete, and Escape for clear.
